Personal meeting ID and personal link are two ways to access your personal meeting room. Your personal meeting room is a virtual room that is permanently reserved for you. You can start it at any time or schedule it for future use. You can also schedule or start an instant meeting with your PMI.
Personal meeting ID (PMI)
Your PMI is assigned to you automatically as a permanent personal meeting room. You can start it at anytime or schedule it for a future use.
Your PMI is part of your personal meeting URL; for example, https://zoom.us/j/5551112222. If you are on a paid plan and have a Pro license, you can customize the 10-digit PMI.
